sabbath

Does anyone really keep the Sabbath day as it says in Exodus 16:29 on the Sabbath day stay in your place don't leave your place so no one can go to church on the Sabbath day as you have to stay in your place of course people will say Jesus healed the blind man on the Sabbath so you can do good...

Hello. This is my very first post. I was baptized into the SDA church in Burbank, Illinois on October 31, 1987. I'd like to get your input on a very basic question. How do you decide what is acceptable to do on Sabbath? How do you define "work"?
